Continuing on MARINE COROSSION AND PROTECTION (Part 1) that we discussed about the Electro-chemical corrosion protection methods and the last remained one is called ICCP system. Reversing the current by creating an opposite potential ( ICCP : Impressed current corrosion protection ) The ICCP system, a large positive current is applied to hull and pass through … Continue reading MARINE COROSSION AND PROTECTION (Part 2)
To understand how marine corrosion protection works, it's necessary to look in more detail in to the corrosion process. In this undesired chemical effect, the material can reach with different chemicals in its surroundings. The reaction can be divided into: Chemical reaction Electro-chemical reaction These reaction take place exclusively at the surface of material. It's … Continue reading MARINE COROSSION AND PROTECTION (Part 1)
Megger test is the test that evaluate the insulation resistance quality. Insulation starts to age as soon as it's made. As it ages, its insulating performance deteriorates. Any harsh installation environments, especially those with temperature extremes and/or chemical contamination, accelerates this process. This deterioration can result in dangerous conditions in power reliability and personnel safety. … Continue reading MEGGER/RESISTANCE TEST
There're three general faults in electric integrity, one by one to go through and we will understand the basic concept of electric installation. Open circuit Fault Due to the broken of conductor (Wire broken) Open circuit will cause the 3-phase Motor stop (Over load relay will trip the motor if the current is … Continue reading Circuit Fault and Electric integrity protection.
